IMPROVEMENT IN w TER-cLosET-suPPLY APPARATUS.

Specification forming part of Letters Patent No. 201,815, dated March26, 1878; application filed J anuary'lfi, 1878."

To all whom it may concern:

Be it known that I, H NRY G. MEYER, of New York city, in the county ofNew York and State of New York, have invented certain new and usefulImprovements in Water- Gloset-Supply Apparatus and I do hereby declarethat the following is a full and exact description thereof, referencebeing had to the accompanying drawings, making part of thisspecification.

Previous to my invention various contrivancesfor supplying water towater-closets have been devised, involving the use of a supply cisternor tank, and in some of such prior contrivances means have been providedto prevent any waste or unnecessary use of the water-supply, while inothers of them the construction has been such that in the event of evena sudden operation of the pull-up'handle there would be an after-wash tothe closet,

and in some these features of construction have been combined so thatthe apparatus has the capacity to prevent undue waste of water, and alsoeffect the after-wash but, in such contrivances as the last mentioned,the construction of the apparatus has been complex and expensive.

To provide for use a Water closet cistern, or water-supply apparatus forwater-closets which shall combine means for both effecting an after-washand preventing any waste of the water, and at the same time be simplerand more economic of structure, is the object of the first part of myinvention, which, to this end, consists in the combination, with themain supply tank or cistern and an auxiliary reservoir, of a passage-wayor means of communication between the main and auxiliary tanks locatedbeneath or formed in the common bottom of said two tanks, all as will beherein after more fully explained.

A further object of my invention is to provide for use an apparatusinvolving the characteristic features of the first part of my invention,together with a service box and means for effecting an after-wash, andat the same time simple in its construction and economic of manufacture;and to this end the second part of my invention consists in. awater-closet cistern, or supply-apparatus having a two-compartment orpartitioned tank or reservoir formed or provided with a passageway orchannel of communication extending from one to the other ofthecompartments, in combination with a service-box, arranged beneath thesaidpassage-way, and suitable valves, all as will be hereinafter morefully explained.

To enable those skilled in the artto make and use myinvention, Iwillproceed to describe the construction and operation of an apparatusembracing it, referring by letters to the accompanying drawings, inwhich- Figure l is a top View, and Fig. 2 a vertical longitudinalsection, of one of my improved water-closet-supply apparatus.

In the several figures the same part will be found designated by thesame letter of reference.

A is the main reservoir; 13, the auxiliary tank, and O theservice-box.

The two water-tanks A and B areformed, it will be seen, of one box,preferably of castiron, having a partition, D, arranged as shown; andthese tanks are connected, as shown, by a' passage-way, E, by preferencecast in the bottom of the box.

The servicebox G is arranged, as seen, beneath a portion of the boxcomprisingthe mainand auxiliary tanks, and communicates with theauxiliary reservoir B at f, where is arranged avalve, G, while at H itis provided with a discharge-pipe, for conducting itscontents to thewater-closet.

I is a valve, for closing that end of the passageway E that opens intothe main reservoir A, the other end of which is always in opencommunication with the auxiliary reservoir B. p

The valves G and I are both suspended by rods, wires, or other meansfrom a lever, J, which is pivoted, as shown, at k, and which hasattached to one end a' wire, cord, or equivalentdevice, l,'extendingdownward toward, and connected to, thelever of the pull-up handle' ofthe water-closet.

The rod or cord lis, by preference, passed rightdown through'the bottomof main tank A, and, as a simple means for perniittlng this without riskof leakage, the usual tube M is employed, fitted water-tight at itslower end to the tank-bottom, and having its upper end located above thehighest level ever occupied by the water in the tanks.

N is the supply pipe or tube, through which water passes to the tanks.This supply pipe is provided at its nozzle or outlet with a suitabletank-regulator apparatus, composed, as usual, of a valve operatedautomatically by the water in the tank A, through the medium of theordinary lever and float P g,- and extending down from the supply-nozzleto near the bottom of tankA is the usual hush-pipe R, through which thewater passes.

The capacity of the passage-way off when the valve G is raised from itsseat is, for purposes to be presently explained, much greater say, threetimes-than that of the dischargepipe H and the service-box G is providedwith a vent-tube or air-tube, S, extending up inside of the auxiliarytank B to a point above the highest level ever acquired by the water insaid tank.

After what has been said of the construction of the apparatusillustrated, the following explanation will make clear its operation.

With the parts of the apparatus in their normal positions or conditions,as shown in the drawings, the communication at f between the auxiliarytank B and service box 0 is closed by the valve G, and the communicationbetween the main and auxiliary reservoirs, A and B is open, the valve Ibeing held up off its seat. Therefore the Water supplied from the main Nwill have supplied both tanks or compartments A and B to the same level,and up to the level at which the float q operates, through the lever P,to shut off the supply, in the usual manner. 4

Now, if the rod or cord 1 be pulled downward by the usual manipulationof the water-closet handle, the lever J will be so oscillated upon itspivotal point or fulcrum at k as to permit the descent of valve I ontoits seat, thus cutting off or closing up all communication between thetanks A and B, while at the same time the valve G will be raised theauxiliary tank B shall have been exhausted.

The air in the service-box O is allowed to escape and re-enter'freely,to facilitate the flow of water, by reason of the vent-tube S beforealluded to, and as soon as the partsshall have been restored to theirnormal positions (thus reseating valve G and unseating valve I) thewater in the main 'tank A will flow through passage-way E into tank B,and, the ball q falling, water will be supplied through nozzle 0 untilboth tanks shall have had'their contents restored to the proper andoriginal level. Since, however, it is not contemplated that the partsshall remain in that condition in which the outflow of water from theapparatus shall occur long enough to empty the tank B, or even longenough to exhaust the greater portion of the contents of B, it followsthat if the water should run out of the service-box O as fast as itentered it, there would be no after-wash-that is, there would be no runof water to the water-closet after the return of the parts to theirnormal condition was permitted by releasement of the pull-up handle ofthe closet; This objection, it will be understood, is overcome by havingthe inlet to the service-box atf made of much greater capacity than theoutlet at H.

Since a great deal more water can rush into the box 0 when it is emptythan can make its exit from said box in the same length of time, itfollows as part of the usual operation of the apparatus that when theworking parts are manipulated in the ordinary manner an ample supply ofwater will rush into the service-box O, and that after the supply tosaid box shall have been cut off, its accumulated contents will bedischarged through pipeH to the water-closet, and the latter thus alwaysreceive an after-wash.

If the communication between tank B and the service-box be eitherintentionally or accidentally kept open longer than is proper ornecessary, no more water than can be contained in the auxiliary tank Bcan possibly be used, and this possible maximum quantity of consumptioncan, of course, be regulated by the size given to the auxiliary tank B.

By the employment in connection with the main and auxiliary reservoirsof a passageway, E, cast in or provided to the common floor or bottom ofthe tanks, the latter, it will be seen, may be made very economically,and will be simple, efficient, durable, and not liable to any leakagefrom joints.

By the arrangement with the two tanks A B and service-box O of thevalves Gr I and claim therein as new, and desire to secure by LettersPatent, is-

1. The combination of the main and auxiliary tanks with a passage-way,E, located at,

or formed in, the common bottom or floor of In testimony whereof I havehereunto set the tanks, substantially as set forth. my hand and sealthis 12th day of January,

2. The combination of the two tanks having 1878.

a passage-way or channel of communication, HENRY O. MEYER. [L. 8.]
